Abstract

The invention relates to a fabrication processing method based on coloring of the surfaces of 3D printed products. The method includes the following steps of 1, the surface polishing procedure of the 3D printed products and 2, the dyeing procedure. The surface polishing procedure includes the steps that a, abrasive materials and the 3D printed products are prepared, wherein the abrasive materials, water and a polishing solution are added to a polishing device and evenly mixed, and a proper number of 3D printed products are placed in the mixture; b, polishing parameters are set, wherein the operating frequency of the polishing device is set to range from 0.5 Hz to 30 Hz; c, the polishing device is started, and the 3D printed products are polished. The dyeing procedure includes the steps that water serves as a medium, dye permeates into the surface layers of the 3D printed products through the heating effect, and the coloring purpose is achieved. The fabrication processing method has the advantages that manpower is saved, and the processing time is effectively shortened; the surface roughness of the 3D printed products becomes controllable and can be selected within a large range; polishing and coloring treatment on the surfaces of the 3D printed products can be conducted under the condition that the size is not changed, and assembly of the products is not affected.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a processing method based on surface coloring of 3D printing products. Background technique [0002] As a kind of rapid prototyping technology, 3D printing technology uses the principle of layer-by-layer superposition and accumulation molding. Because it is "additive" manufacturing, its structural design is almost not affected by the processing method. Designers can also use their unrestrained imagination to design a variety of products. With the popularization of 3D printing technology, the application of 3D printing consumables is becoming more and more extensive. As a kind of printing consumables, nylon has many advantages such as high strength, good chemical stability, and good wear resistance. It is also the preferred material for industrial-grade 3D printing. However, for products, due to the limited printing principle, the surface roughness of 3D printed ...
